Assuming that your lists_relay is intended to whitelist outgoing
messages from Mailman, the -bounces entry should be sufficient as all
messages from Mailman are sent with envelope from SOMELIST-bounces or
mailman-bounces except in one rare circumstance, notices of
mailman-bounces bounces are sent with envelope from mailman-loop.
I see two ways you can deal with this automatically.
If you are comfortable with Python, you could modify
Mailman/MTA/Postfix.py to write a third files containing the
information you want and call postmap to update the corresponding hash
database.
Perhaps a simpler solution is to set POSTFIX_MAP_CMD which defaults to
'/usr/sbin/postmap' to point instead to a shell script which does
/usr/bin/postmap $1
followed by a sed or whatever to create the file you want by editing
the virtual-mailman file and finally by another postmap to update the
hash db.
